blanks by hand for future operations. Obviously a device which'willstackthe blanks at the time that they are formed will produce a considerablesaving in obviating the hand stacking. r

The object of this invention is to provide a simple and inexpensivedevice for stacking blanks at the time that they are formed.

In accordance with the general features of V the invention there isprovided a chute which =7 abuts against the die of a, punch press andconducts blanks punched therethrough away in an orderly fashion intoengagement with stacking rods for stringing the blanks. The

7 cross section of the chute conforms substantially to that of theblanks in order to align the blanks in a stacked formation, and meansare connected to the chute for preserving this,

' Springs 28. are attached to, the end .of the order. r A clearunderstanding of the invention will be had from the followingdescription of one specific embodiment thereof when taken in connectionwith the accompanying drawing, wherein V Fig. 1 is an elevational viewof the apparatus as used with-a punch press: I

Fig 2 is a sectional view of the apparatus taken on line 22 of Fig. 1;

Fig. 3 is detail view ofthestacking rods; Fig. 4 is a view showing howthe stacking rods are used after they are filled, and

Fig. 5 is a detail view of a retarding block. Referring now to thedrawing in which like numerals designate similar parts throughout theseveral views, there is dis closed an ordinary punch press which is oneof a number of part or blank forming machines with which the improvedmagazinmg structure may be used. The press 15 possesses the familiaressential components of a punch press, consisting of a punch 16,

to a: cr0ssbar36 within a counter 17 for supporting a sheet of stock 18,and adie 19 having an aperture 20 through which the 'punch forces aportion of the stock 18. to form blanks therefrom.-

The improvedi magazining' or stacking structure comprises achute 22which is con nected by brackets .23 and screws 24 to the bottom of thedie 19. This chute "provides an inner. passageway orjguide'way '25 whichconforms in cross sectionto the outline of emeo wns'rERN" ELECTRICthedie aperture 20 and thebrackets 23 positionthe chute 22 s01'that--the passageway25 cooperateswith the die aperture 20 and receives thepunched'blanks, in the same position' in which they are? blanked,withoutallowing them to'be turnedaround or about themselves. Thus, it'isto be understood-that V the passageway 25 is designed to conduct thesuccessively punched blanks away from the die 19 in an orderly fashionand to align them fully below. a i

in a "stacked formation, as will appear more Thechute22curves outwardlyat its lower end and is-connected to table 26 by a band 88, and thistable ha'sa top 27 which is adapted to engage the blanks and. conductthem therealong as they leave the end o'fithechute.

chute for resiliently engaging the formed parts and preventing them frommovingout of t-hechutetoo rapidly, as further noted'bee low. On topofthe .table26'there is disposed a pair of stringing rods29- forengagingthe blanks as they movegalong the table, and these rods are-usedtoremovethe stacked parts to other apparatus for furtheroperations."

. The chute f22-is constructed, as shownin Fi g. 2, of twocrosspiecesEOa-nd3-1 secured by sideplates82 and screws 33; The cross pieces 30 and31 form the passagewayi25 approximating infcross sectionthe outline of aformed blank .34. Y glhese formed blanks usually pos+ sees a number ofholes 35, and the stringing rods 29 readily engage the holes and securethe blanks in a stacked formation produced by the guideway or passageway255 The of the magazining or stacking structure, it is preferable tokeep the chute 2 filled at all times with a continuous column of theblanks 3a in order that the blanks may have no chance of turning aboutthemselves or becoming disarranged in the passageway 25. In order tothus fill the chute 22 at the starting of the operation, aretarding'block 40 having lateral springsll, of which only one is shownin Fig. 5, is first inserted within the die-aperture 20. The punch 16 isthen actuated to punchsuccessive blanks from the stock 18 into thepassageway 25 of the chute, and this. punching of the blanks, of course,gradually forces'the block L0 to the bottom of the chute. Thus it isapparent that the chute becomes filled with the blanks, and. due to thefact that the passage way 25 conforms in crosssection substantial 1y t0the cross-section of the blanks 34, the blanks become arranged into astacked col- In the operation After the column of blanks is thus formedthe springs 28 at the bottom'of the chute engage the lowermost blanks ofthe columnand retain the blanks within the chute to preserve the column,and the retarding block 40 is removed because it is no longer necessaryin w in Fig. 41 The stacked blanks are inverted.

the, operation. From now on the operation of the stacking chute 22 isapparent. Blanks are continuously punched into. the top of the chute bythe punch 16, and as each blank is 'punchedtherein the column of blanksin the chute is forced downwardly the thickness of one blank, and ablank is'forced past the prings28 at the lower end of the chute.ontinuous successive punchingsof the blanks force many blanksout pastthe springs 28. and onto the table top 27 which conducts the blankgintoengagement with thestringing rods 29which engage the holes 35 in theblanks. 'Finally the stringing rods 29 become filled with the stackedblanks and are replaced by other similar rods.

The stringing rods 29 are particularly" applicable for emptying thestacked blanks into a magazine, such as the one designated 42 over thismagazine andinserted' therein when the stringing rods 29 are readilyremoved leaving the blanksstacked in the magazine and ready for further.operations, such as roll formingby a rolling machine 43. 7

Thus it isbelieved to be apparent from theabove description that theinvention provides a simple structure for efliciently stacking theblanks and produces a considerable saving by dispensing with stacking byhand when the blanks are indiscriminately passed from the punch press.Furthermore, the novel structure also. produces a significant savingwhen the parts blanked are thin or bendable when'they would be rendereddefective vin casethey'were mixed; together in a pile. Of

course, the structure shown may be modified in various ways, as forinstance it may be al tered to stack difierent shaped blanks, or it maybe constructed with adjustable parts so tured parts successively formedby amachine,

comprising a chute for receiving the parts from themachme having itsrecelvlng end extending vertically and its discharge end extendinghorizontally, a horizontally disposed supporting member positioned ingeneral alignment with the discharge end of the chute and having itsupper surface receivable in the recesses of the parts when passing fromthe chute for maintaining the parts in stacked formation, and a headedstringing member supported parallel to said upper surface by its headand by said parts.
